In the title compound, C 13 H 10 N 2 O 3 , the dihedral angle between the planes of the two aryl rings is 7. 42 (10) . An intramolecular O-HÁ Á ÁN hydrogen bond generates an S(6) ring. The crystal structure features C-HÁ Á ÁO hydrogen bonds. Structure descriptionWe report here the synthesis and characterization of the title Schiff base derivative (Fig. 1)) prepared from the condensation reaction of an equimolar proportion of 5-nitrosalicylaldehyde and aniline in CCl 4 . The diversified nature of salicylaldehyde derivatives containing Schiff bases as an integral part of the structure exhibit a variety of important biological properties, including anti-bacterial, anti-cancer and anti-tumor activities (Ida Malarselvi et al., 2016).The benzene and phenyl rings are inclined at 7.42 (10) to one another. The molecule has an E conformation about the C N bond, and the C5-C7 N2-C8 torsion angle is À177. 03 (16) . The 4-nitro group is slightly tilted away from the benzene ring to which it is attached [O1-N1-C1-C2 = À5.8 (3) and O2-N1-C1-C6 = À2.7 (3) ]. The strong intramolecular O3-H3AÁ Á ÁN2 hydrogen bond (NÁ Á ÁH distance of 1.83 Å ) generates an S(6) ring. The strong band in the IR at 1632 cm À1 is assigned to the C7 N2 stretching frequency of the imine group of Schiff base with the C7 N2 bond distance of 1.276 (2) Å indicative of double-bond character. The crystal structure features C2-H2Á Á ÁO1 and C7-H7Á Á ÁO2 hydrogen bonds (Table 1, Fig. 2). Yan et al., (2014) have reported the crystal structure of 4-bromo-2-[(phenylimino)-methyl]phenol, in which the molecule is essentially planar (r.m.s. deviation = 0.026 Å ).
